ARM F OR FOLDING STEAlVlER-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 271,248, dated January30, 1883,

Application filed October 13, 188]. (No model.) i

To all whom it may concern Be it known that we, FRANK G.- JouNsoN andJOHN H. HAYWARD, citizens ofthe United States, residing respectively inthe city of V Brooklyn, in the county of Kings and State of New York,and at Northfield, in the county of Richmond and said State of New York,have invented new and useful Improvements in Armsfor FoldingSteamer-Chairs, of which the following is a specification.

The object of our invention is to increase the comfort and convenienceof travelers. upon ocean, river, and other steamers, which we accomplishby providing such arms for folding steamer-chairs as can be attached,detached, and extended and rotated in such a manner that they maybeemployed not only as arms proper, but as tables for various uses, asfor writing, reading, lunching, card-playing, 850.

The peculiarities of our invention relate, first, to the manner ofattaching and securing the arms to the chair, wherebythey can beinstantlydetached therefrom whenever the chair is to be closely foldedfor packing it away; second, to their construction in such a manner thatthey can be rotated and held in a hort zontal positlon for the purposesabove enumerated; and, third, so they can be adjusted backward and forthhorizontally, that they may be placed in the most favorable positionwhen employed as tables.

The following is a full, clear, and exact description of theconstruction and operation of our invention, reference being bad to theaccompanying drawings, in which Figure 1 represents a side view of oneof the arms placed in the ordinary vertical position Fig. 2, a frontview with the arms in a verticalposition; Fig. 3, a vertical sectionthrough the line 00 m of Fig. 1; and Fig. 4, a downward View with thetable part of the arms placed in a horizontal position, one being turnedoutward and the other inward.

The method of constructing the arms and attaching them to and detachingthem from the chair is thus described: A is a continuous frame, beingmade wider on the top than in its other parts to furnish morebearing-surface for the arm of the occupant of the chair, as seen 50 inFigs. 2 and 3. Extending across and fastened to .this frame A iscane-work a, Figs. 1 and 3, or other suitable material. The object ofplacing this cane-work a in the central line of the frame A is tofurnish a rim or guard to prevent articles which may be placed thereonfrom sliding off when the revolving part of the arm is employed as atable. This frame A, which we will term the table-frame, is fastened tothe base or carrying piece, E, by means of the metallic brackets O andD, Fig. 1. The lower ends of these brackets are fastened to the carryingpiece E by means of "screws. (Shown in Fig. l.) The bracket 0 supportsthe front end of the table-frame A, to which it is secured by a pin, 0,which passes through and revolves in the bracket O. The bracket Dsupports the back end of the table-frame A, to which it is secured by aclamp bolt and nut, 61'. The pin 0 and clamp-bolt 61' stand in line witheach other, upon which rotates the table-frame A. The table A is held inany desired position, vertical or horizontal, bv'

means of the ratchet or notched coupling (1 d, onehalf of which, d, issecured to the tableframe A and the other half, d, to the top of thebracket D.

Whenever it is desired to turn the rotating part of the arm A fromavertical to ahorizontal position, or vice versa, it is only necessaryto turn the clamping-nut 61' back far enough to allow theratchet-coupling d d" to work upon itself. The table A is then held inposition by again tightening up the ratchet-coupling with the clampmutd.

The two tables A A, as shown in Fig. 4, can be turned into a horizontalposition either way-that is, so the widest part of the arms will standoutward or inward from their cen ters of motion.

The carrying-piece E is placed upon and fast- 0 ened to the side bar, H,Figs. 1 and 3, of the seat of the chair in the following manner: Thecarrying-piece E, which in shape corresponds with the side bar, H, ofthe seat, has a long slot,

F, faced with metal around its edges. The 5 back end of this slot isenlarged into a round opening, as shown in Fig. 1, to allow it (thecarrying-piece E) to pass over the clampingnut g. Thisclampiug-nutgworks on a threaded post fastenedinto the side bar, H, ofthe seat. I00

2 'eamas To place the carrying-piece E upon the side bar of the seat itis only necessary to pass the enlarged opening of the slot F over theclampnut g and slide it (the carrying-piece E) back and tighten up theclamp-nut g, which binds the piece E to the side bar, H, of the seat.

As an additional security to keep the carryin g-pieceE in position,thereis provided on the outside of the side bar, H, a wood or metallicrib. (Shown in Fig. 1 by the dotted lines 0 e, and the end of which isshown at e in Fig. 3.) Corresponding to this rib eeis a groove cut inthe carrying-piece E,which fits and works upon the rib.

When it is desired to move the -entire arm forward to give the occupantof the chair more room behind the tables, when they are placedhorizontally for use, itis only necessary to ease the clampnut g andslide the carrying-piece E as far forward as required, and then tightenup the not 9. By thus sliding the pieces E E as far forward as the slotsF F will permit, the tables A A can both be turned horizontally, withthe wider part inward, thus forming a double table in front of theoccupant of the chair.

Either or both of the tables can be turned with the wider part outward,whatever be the position of the carrying-pieces E E, and thus providetables at the side of the occupant of the chair.

When it is desired to wholly remove the entire arms from the chair forwhatsoever purpose, it is only necessary to ease the clamp-nut g andthen slide the carrying-pieces E E forward until the clamp-nut passesthrough the enlarged openings of the slots F F.

We are aware that adjustable and detachable arms and book-rests ofchairs are not new. Therefore we do not claim broadly an adjustable ordetachable arm to a chair; but

What we do claim as new, and desire to secure by Letters Patent, is-

1. In a folding chair consisting of an X- frame, the sliding piece E,having the slot F, with an enlarged opening at the back end of the same,in combination with a table and the side rail, H, of the seat of thechair, having the rib e e, substantially in the manner and for thepurposes described.

2. In a folding chair consisting of an X- frame, the rotating tables AA, mounted upon and in combination with the adjustable carrying-pieces EE and the brackets O D, substantially as and for the purposes set forth.

3. In a folding chair consisting of an X- frame, the combination of thecarrying-piece E, having the slot F, with an enlarged opening at theback end of the same, the clamp nut g, the rotating table A, brackets GD, and ratchetclamp d d", and clamp-nut d.
